v HTTOF/VE) PACKING FOR FRANGIBLE ARTICLES Thomas C. Nurre, Downers Grove,'lll'., assignor to International Paper Company, New York, N. Y., a corporation of New York Application January 11, 1956, Serial No. 558,463

3 Claims. (Cl. 20662) This invention relates in general to packing for frangible articles and in particular to a new and useful packing made of corrugated paperboard or the like which is easily adaptable to cushion and support frangible articles of varying sizes and shapes.

Previously packing for articles such as glass windshields, plates, etc., was fitted to the article as by a plurality of separately inserted pads and braces in order to provide support and protection to the article during shipment. Packing constructed in accordance with this invention is formed by cutting out a portion of the packing material to form rows of tooth-like projections between which the frangible article is inserted. The cutting is done so that the tooth-like projections in each row will bear against the article that is inserted therebetween and effectively support and cushion the article against any jarring or shock. Slight variations in the configuration of articles to be packed are provided for by bending the projections to permit the article to fit between opposite projection rows. Greater variations are provided for by changing the alignment and spacing of the projection rows.

Accordingly, it is an object of this invention to provide a packing for the floating support of frangible articles.

It is a further object to provide a frangible article packing formed by cutting out a portion thereof to form toothlike projections arranged in opposite rows to bear along the surface contours of an article wedged therebetween.

A further object is to provide a packing which is simple in design, rugged in construction and economical to manufacture.

With these and other objects in view, the nature of which will be more apparent, the invention will be more fully understood by reference to the drawings, the accompanying detailed description andthe appended claims.

In the drawings,

Fig. 1 is a perspective view of packing constructed in accordance with this invention arranged to protect a windshield;

Fig. 2 is a perspective view of another embodiment of packing constructed in accordance with this invention arranged to protect a curved glass plate; and

Fig. 3 is a vertical sectional view taken on the line 33 of Fig. 2.

Referring to the drawings in particular, the invention as illustrated includes a shipping container 9 (shown in dotted line outline) and a pair of packing members 10 and 12 made of corrugated paperboard or the like, positioned at each end of a large curved plate glass Wind shield 13. The packing members 10 and 12 are arranged in the positions they assume when the complete assembly is in place in the container 9 and hold the windshield away from contact with any of the container walls.

The packing members 10 and 12 are symmetrically opposed and each includes a pair of spaced parallel in wardly directed panels 14, 14 connected by a vertically disposed panel 16. Each of the panels 14 is provided along its front and rear edges with an upstanding flap 1::

provided at its inner edges with a securing tab which is fastened to a flap 22 extending across the inner end of.

the panel 14. Each of the flaps 22 is notched as at 24 adjacent the flap 14 to permit entry of a windshield or other article to be supported by the packing members.

' Each vertical panel 16 is provided along its front and rear edges with an outwardly extending flap 26. The depths of the flaps 18 and 22 and the width of the fi'ap 26 aresuch as to insure spacing of all parts of the supported article away from all of the wall portions of the, surrounding;- container.

Inaccordance with the invention the panels 14 of the packing members 10 and 12 are cut out in a novel manner to provide two opposite rows A and B of enlarged serrated projections designated 28- in row A, and inwindshield 13 to fit tightly therebetween. The projections 28 are in this instance offset from the projections 30. However, they may also be made with their tips in alignment, provided suflicient spacing is provided between rows A and B to accommodate the windshield 13 either with the ends of the projections straight or displaced slightly.

The rows of projections and the notches 24 are formed by die-cutting the panels 14 and the flaps 22. In the event there is not sufiicient room between the rows for the windshield a fit may be achieved by bending any of the projections 28 or 30 to provide space for the windshield while still providing bearing surfaces which are effective to support the windshield and cushion it from shock.

In the embodiment shown in Fig. 2 two upright panels 32 and 34 are cut away in accordance with this invention to provide a packing for a curved glass plate 36. Two opposite rows C and D of projections 38 in row C and 40 in row D are formed on each of the panels 32 and 34. The projections 38 are oifset from the projections 40 and rows C and D are made close enough together so. that the projections 38 and 40 must be bent to permit insertion of the plate 44 between the rows. The degree of bending may be more severe in cases where the disposition of rows C and D does not exactly conform to the configuration of the object being packaged. In any event the purpose is to hold the article by frictional engagement with the projections. Whenever the form of packing illustrated in Figs. 2 and 3 is employed it will be appreciated that additional padding will be provided at the ends to cushion the glass against endwise shock.

Thus it can be seen that the invention provides a packing which may be easily cut in a novel manner to provide many contacting supporting projections which cushion and support a frangible article of most any size and shape. Small variations in configuration and size may be taken care of by proper positioning of the projections formed in the cut portion as by bending them, while large variations in size and shape are handled by changing the spacing or positioning of the rows of projections. The point support of the frangible articles at the edges of the projections provides excellent means for distributing and absorbing jarring stresses or shocks without damaging the packaged article. By making a packing in accordance with this invention it is possible to provide standard packing sizes with cut away portions adaptable for use with a great variety of types and shapes of articles to be packaged.

While a specific embodiment of the invention has been shown and described in detail to illustrate the application of the invention principles, it will be understood that the invention may be embodied otherwise without departing from such principles.

I claim:

l. A package comprising an outer container having front, back, top, bottom and side walls, a Windshield in said container, a packing in said container including two opposed pairs of panels disposed in spaced parallel relation, each panel of each pair including a portion cut away to define two'opposite rows of serrations arranged to receive a portion of said windshield, and flaps carried by each of said panels to space said panels and said windshield away from said container walls whereby to maintain said windshield supported by said serrations out of contact with said walls.

2. A generally U-shaped article-supporting packing for shipping containers including a pair of panels disposed in spaced parallel relation and a connecting panel extending therebetween, each of said parallel panels including a portion cut away from the free end thereof to define two opposite rows of serrations adapted to receive a portion of an article to be supported, all of said panels being provided along each of their free edges with a spacer flap extending outwardly in a direction normal to the general plane of its associated panel.

, allel panels each being provided with a spacer flap extending outwardly in a direction normal to the, general plane of its associated panel, and the free end edges of said parallel panels each being provided with an outwardly extending end flap having its ends connected to the adjacent ends of the flaps on the side edges of said panels, each of said end flaps being provided with an aperture aligned with the adjacent end of the cut-out portion of its associated panel.
